    Calcite Precipitation on Excavated Andesite Surfaces From the Archaeological Sites of Aigai and Assos (turkey)
    (Springer Heidelberg, 2024) Kaplan, Caglayan Deniz; Boke, Hasan
    The conservation interventions of crusts or patinas formed on the surfaces of stone monuments should be evaluated within a comprehensive approach in archaeological excavations, taking into account their material characteristics. In this study, the mineralogical, chemical and microstructural characteristics of whitish crusts formed on the surfaces of buried and later excavated andesite surfaces at the archaeological sites of Aigai and Assos (Turkey) were investigated by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray fluorescence (XRF) and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) analyses in order to establish a conservation approach at the archaeological sites. The whitish crusts formed on the excavated andesite surfaces are mainly composed of calcite with freshwater diatom species. Calcite is most likely formed by the alteration of plagioclase by carbon dioxide in the soil during the burial of the andesites. In the soil, CO2 reacts with plagioclase to produce kaolinite and calcite which are precipitated on the andesite surfaces after excavation. The presence of freshwater diatom species in the whitish crusts may indicate that the andesite remains were buried in the waterlogged soil for many years and later excavated. Therefore, whitish crusts should not be cleaned from the andesite surfaces, as they are a sign of the burial history of the monuments and a protective layer against weathering.

    Evolution of a Medieval Castle Town and Its Landscape in the Southwestern Anatolia
    (ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2023) Etlacakuş, Aysen; Turan, Mine Hamamcioglu
    The objective of this paper is to develop a framework for understanding the archaeological sites composed of the remains and traces of castle towns and evaluating these sites together with their landscapes with a retrospective focus. A case study approach was undertaken with a focus on Kale Tavas (Tabae) in the Southwestern Anatolia. The scope of the Historic Landscape Characterisation was adapted to characterise the remains and traces of the castle town together with its landscape. Site survey at different scales, archive research, and in-depth interviews were used to acquire data. Our results suggest the related conservation boundaries should be determined not only considering the citadel walls but also the natural context that had contributed to the evolution of the castle town. For Kale Tavas, heritage management should be planned by considering the values of the historical landscape and the factors that threaten them, as this study shows.
